Question

1. Find Each Right triangles missing length. If necessary, round to thenearest tenth,5 pointsleg =8 cm, leg= 21 cm

Answer 1

We have a right triangle, for which we know the two legs.

We can calculate the hypotenuse H by applying the Pythagorean theorem:

$\begin{gathered} H^2=L^2_1+L^2_2=8^2+21^2=64+441=505 \\ H=\sqrt[]{505}\approx22.5 \end{gathered}$

The missing length (the hypotenuse) is approximately 22.5 cm.
